What were the different B2C business models?
They were the three or four Cs: Connectivity, or Communication (like an ISP); Content (a portal, FT.com, MapQuest); Commerce (Amazon); and Community (such as ... well, Community disappeared rather quickly). In practice, these propositions overlap. AOL gives you ISP connectivity and portal content, and tries to sell you stuff. Napster was free content and might become commerce. Portals support communities - for example, game players.
